Description

  The present invention relates to a stand-up electric vehicle, and more particularly, to a stand-up electric vehicle with an improved body structure.

  One-wheel and two-wheeled standing electric vehicles have become popular in recent years, but one-wheeled standing electric vehicles are not stable and can easily fall over, while two-wheeled standing electric vehicles move the center of gravity of passengers. Can be detected to change the driving state (speed) of the wheel, but in the control such as the direction change, the passenger must operate the steering wheel by hand.

  However, the conventional two-wheel standing electric vehicle structure does not consider the centrifugal force applied to the occupant's body when changing direction, so the occupant firmly grasps the handle with his hand during the change of direction. However, it is necessary to maintain the posture of the body while there is a possibility that the occupant may become tense and erroneously operate the steering wheel, and the erroneous operation may cause the vehicle to fall.

  Furthermore, the handle of the conventional two-wheel standing electric vehicle is arranged in front of the passenger, and when it is about to fall while moving forward, it tries to be passive by jumping forward. In some cases, however, a more dangerous situation may occur where the handle falls over while being entangled with the handle.

  An object of the present invention is to provide a stand-up electric vehicle with improved safety in view of the drawbacks of the conventional stand-up electric vehicle.

  As a means for achieving the above object, the present invention provides a vehicle body block to which a front wheel capable of traveling in the front-rear direction and a control means for controlling the driving of the front wheel are attached, one in the left-right direction substantially perpendicular to the front-rear direction. A stand-up electric vehicle characterized by being pivotally supported one by one is provided.

  According to the above configuration, the standing riding electric vehicle according to the present invention is provided with the front wheel and the control means for controlling the driving of the front wheel respectively attached to the left and right body blocks, and the left and right body blocks. The rider puts his / her feet on the left and right body blocks, and moves the left and right body blocks to each other while moving the center of gravity. Since it can be made to move, it can comprise so that the drive state of the front wheel attached to the said vehicle body block may be changed according to the rotation state of each vehicle body block. As a result, the driving state of the front wheels attached to each body block becomes independent, so the passenger can change the direction by moving the center of gravity without relying on the steering wheel, and erroneously operating the steering wheel It is possible to prevent the occurrence of falls caused by the above.

  Hereinafter, preferred embodiments of the electric motor vehicle according to the present invention will be described in detail with reference to the drawings.

  1 to 7 show a first preferred embodiment of the electric vehicle for standing up according to the present invention. FIG. 1 is a perspective view showing an external configuration thereof, and FIG. 2 shows an internal configuration thereof. FIG. 3 is a partially enlarged cross-sectional view showing the configuration of the first pivoting means of the first preferred embodiment, and FIGS. 4 to 7 show its control method. It is explanatory drawing which is.

  As shown in FIGS. 1 and 2, the standing electric vehicle according to the present invention includes a front wheel 800 that can travel in the front-rear direction, a control unit 804 that controls the driving of the front wheel 800, and is controlled by the control unit 804. The vehicle body blocks 3 to which the driving means 802 for driving the rotation of the front wheels 800 are attached are provided one by one in the left-right direction substantially perpendicular to the front-rear direction, and each vehicle body block 3 is relatively It is configured to be pivotally supported. That is, a passenger who stands on the vehicle body block 3 can change the posture of each vehicle body block 3 by tilting one of the vehicle body blocks 3 forward or backward in the front-rear direction.

  In the first embodiment, the vehicle body block 3 has a footrest 31 on which an occupant can put his / her foot on the upper surface, and a handle 2 extending in a vertical direction substantially perpendicular to both the front-rear direction and the left-right direction. Installed. A front wheel 800 attached to one vehicle body block 3 is actuated by driving of a drive means 802 controlled by a control means 804 attached in the relevant vehicle body block 3, and the control means 804 is a vehicle body. A gyro sensor that senses the posture of the block 3 is provided, and the driving state of the front wheels 800 can be changed according to the sensing result of the gyro sensor.

  Further, as shown in FIG. 2, the left and right vehicle body blocks 3 are first pivotally mounted between the left and right vehicle body blocks 3 so as to extend in the left-right direction. 4 is pivotally supported. As shown in FIG. 3, the first pivot means 4 is a first pivot fixed to one of the left and right body blocks 3 (the left body block 3 in the figure). The first support pipe 41 is fixed to the other one of the left and right body blocks 3 (the right body block 3 in the figure) and is inserted into the first pivot section 41. 1 pivot support shaft portion 42, and a bearing portion 43 attached so as to be interposed between the first pivot support tube portion 41 and the first pivot support shaft portion 42 in the first pivot support tube portion 41. It is comprised so that it may comprise.

  Further, as shown in FIG. 4, the control means 804 controls the drive means 802 to drive the front wheels 800 forward when the vehicle body block 3 is tilted forward according to the sensing result of the gyro sensor. Then, as shown in FIG. 5, when the vehicle body block 3 is tilted rearward, the front wheel 800 is driven to travel rearward. That is, as shown in FIG. 4, when both the left and right vehicle body blocks 3 are tilted forward, the control means 804 attached to the left and right vehicle body blocks 3 are also driven at the same time. Since the vehicle 802 is controlled so that the front wheel 800 travels forward, the standing electric vehicle of this first preferred embodiment goes straight forward, and one left and right as shown in FIG. When each vehicle body block 3 is tilted backward, the control means 804 attached to each of the left and right vehicle body blocks 3 also controls the drive means 802 so that the front wheels 800 travel backward. Therefore, the standing riding electric vehicle according to the first preferred embodiment moves backward.

  Furthermore, as shown in FIG. 6, when only the left body block 3 of the left and right body blocks 3 tilts forward, only the control means 804 attached to the body block 3 tilts forward. However, since the driving means 802 is controlled so that the front wheel 800 travels forward, the standing riding electric vehicle of this first preferred embodiment turns to the right and is shown in FIG. When only the right body block 3 of the left and right body blocks 3 tilts forward, only the control means 804 attached to the body block 3 tilting forward moves the drive means 802 and the front wheel 800 forward. Therefore, the standing electric vehicle according to the first preferred embodiment turns to the left side.

  Of course, whether the left and right vehicle body blocks 3 are inclined forward or backward is controlled by the movement of the center of gravity of the passenger who puts his / her legs on the footrest 31 on the upper surface of the vehicle body block 3. The rider of the standing riding electric vehicle can control the forward and backward movement and the direction change by moving the center of gravity without relying on the handle, and can prevent a fall caused by an erroneous operation of the handle.
